Class Time

java.lang.Object

manifold.science.api.AbstractMeasure<TimeUnit,Time>

manifold.science.measures.Time

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<Time>, java.time.temporal.TemporalAmount, Sequential<Time,Rational,TimeUnit>, ComparableUsing<Time>, Dimension<Time>

public final class Time
extends AbstractMeasure<TimeUnit,Time>
implements java.time.temporal.TemporalAmount

Models a duration of time in units of TimeUnit.

Use values of Time directly in arithmetic expressions with other dimensions such as:

   // commonly used unit abbreviations e.g., m, ft, hr, mph, etc.
   import static manifold.science.util.UnitConstants.*;
   ...
   Time duration = 5.2 hr;
   Time mileTime = 4 min + 12.78 sec;
   Length distance = 80 mph * 2.3 hr;
 

Like all dimensions in the manifold.science.measures library, the Time dimension is unit-independent, which means you can work with any combination of TimeUnit such as Second, Hour, and Day, because all operations on Time are maintained internally using standard SI units.

 Time seconds = 12.7 s;
 seconds = seconds + 5.2 hr; // add hours to seconds
 

Time implements TemporalAmount so you can easily work with Java's java.time library:

   LocalDateTime date = LocalDateTime.of( 2018, 10, 17, 17, 35 );
   LocalDateTime yearLater = date + 1 yr;
   LocalDateTime tomorrowOneHourLater = date + 1 day + 1 hr;

Method Detail

getBaseUnit

public TimeUnit getBaseUnit()

Description copied from class: AbstractMeasure

The unit on which all instances of this type are based. For instance, a Length dimension might use Meters as the base unit because it is the SI standard.

Specified by:

getBaseUnit in class AbstractMeasure<TimeUnit,Time>

make

public Time make(Rational value,
                 TimeUnit unit,
                 TimeUnit displayUnit)

Description copied from class: AbstractMeasure

Creates a new instance using the specified parameters.

Specified by:

make in class AbstractMeasure<TimeUnit,Time>

make

public Time make(Rational value,
